摘要:	We reassess the B -> pi l nu(l) differential branching ratio distribution experimental data released by the BABAR and Belle Collaborations supplemented with all lattice calculations of the B -> pi form factor shape available to date obtained by the HPQCD, FNAL/MILC, and RBC/UKQCD Collaborations. Our study is based on the method of Pade approximants and includes a detailed scrutiny of each individual data set that allows us to obtain vertical bar V-ub vertical bar = 3.51(8)(stat)(7)(syst) x 10(-3). The semileptonic B+ -> eta(('))l(+)nu(l) decays are also addressed and the eta-eta' mixing discussed.
